STEAM-JET PUMP.

SPECIFICATION forming part of Letters Patent No. 475,716, dated May 24, 1892.

Application filed August 13,1891. Serial No. 402,560. (No model.)

T all whom t may Concern,.- fl, l0, and ll indicate concentric pipes which Be it known that I, JAMES A. BILLS, a citizen extend into the chamber 1 at a point opposite of the United States, residing at Chicago, in the nozzle 7, as shown in Fig. l. The largest the county otl Cook and State ot Illinois, have pipe 9 is provided with external screw-threads 55 invented certain new and useful Improvel2 at one end,which are adapted to be screwed inents in Steam-J et Pumps, of which the folinto threads formed in the box 3, by means lowing is a specication,reference being had ot' which the pipe 9 is securedin place, The to the accompanying drawings, in whichpipes l0 and ll are each provided .with iins Figure l is a central longitudinal vertical 13. The fins upon the pipe progect. suili- 6o io section, and Fig. 2 is a vertical cross-section ciently from said pipe to engage the inner on line 2 2 of Fig. l. surface of the pipe 9, and the fins upon the My invention relates to steam-pumps, and pipe ll project sufficiently to engagetlie ininore particularly to that class of steain ner surface of the pipe l0, whereby the Sevpumps which are designed to be used in pumperal pipes are securely held in place. Fach 65 ,ing sand, mud,or other heavy inatterin which of the pipes l0 and 1l is preferably provided the power of steam operates directly to do the with three iiiis, as indicated in Fig. 2; but, if work of pumping. desired, the number may be Varied, and in- The object of my invention is to provide a stead of providing continuous fins lugs may new and improved pump of this description be cast on the exterior surfacesof the pipes 70 zo which may be used in pumping sand or mud at suitable points to secure the pipes in place. and which will be both cheap and etlicient. The end of each of the pipes 9, 10, and l1 I accomplish this object as hereinafter speciwhich projects into the chamberl is lared,as fied, and as illustrated in the drawings. That shown, so as to present a larger opening for which I deem to be new will be pointed out the admission of the sand or other matter. 75 in the claims. le indicates a coupling which is screwed In the drawings, l indicates a chamber, upon the outer end of the pipe 9, Which exwhich is connected by means of a pipe 2 with tends through the side wall of the box 3, as the supply of matter to be pumped. The shown, and is screw-threaded to receive the chamber l is preferably rectangular in shape coupling. A pipe for delivering the sand or 8o 3o and is formed by securing a plate 4 upon a mud to any desired point may be connected metallic boX 3. The points of contact of the With the pipes 9, l0, and ll by means ot' the edges of the box 3 and plate 4 are made to i"it coupling la in the usual manner. The outer tightly, so that the chamber l may be heiends of the pipes l0 and 11 extend a short disnietically sealed. The box 3 and plate i are tance beyond the outer end of the pipe 9, as 85 3 5 preferabiy secured together by means of bolts shown. The inner ends of the pipes 10 and 5, as shown in the drawings. ll terminate at successively greater distances 6 indicates a steam -pipe, which extends from the nozzle 7, as shown in Fig. l, and the through a suitable opening in one side of the several pipes are of such diameter that a narbox 3 into the chamber l and is fitted tightly row space will be left between each of the 9o 4o in the side of the box through which it propipes, as shown. The supply-pipe 2 is pref jects. The end of the pipe 6 which extends erably located ata point under the end of the into the chamber l is contracted, as shown nozzle 7 and the opening into the pipe 9, as at 7 in Fig. l, to forni a nozzle, so that the best shown in Fig. l. I steam as it passes through the pipe 6 will The operation of my improved pump is as 95 issue from the pipe in the forni of a fine jet. folle ws: A supply of steam under pressure is S indicates screw-threads which are formed supplied through the pipe 6 and is directed in the exterior portion of the pi pe 6, as shown from the nozzle '7 into the pipe ll. This creates in Fig. 1, which screw-threads are adapted to a vacuum in the chamber l, causing an iiiscrew into threads formed in the side of the ilow of the sand and water or mud through roo 5o box 3, whereby the pipe 6 may be adjusted the feed-pipe 2 into the chamber. The conlongitudinally. tinued action of the steam-jet will then cause a flow ofthe sand or mud through the several pipes 9, 10, and l1 into the delivery-pipe at the outside of the pump, through which it may be carried to any desired point. The peculiar arrangement of the pipes 9, l0, and ll causes a division of the particles of sand-and mud and prevents its becoming packed at any point and also subjects the sand or mud in smaller particles to the action of the steam, and it is thereby carried much more easily than it would be if it were carried in a solid mass. After the sand has reached the delivery-tube it is subjected to the direct action of the steam and may then be forced along more readily in mass. lVhen it is desired to gain access to the interior of the chamber, the plate 4 may be removed by loosening the bolts 5.

By constructing the pump as above described I am enabled' to pump water containing a much larger percentage of sand or mud than it has heretofore been possible to pump and also to raise it higher.

That which I claim as new, and desire to se cure by Letters Patent, is-

1. v The combination, with a closed chamber having a supply-pipe at one point and a delivery-pipe, of a steam-pipe extending into the chamber and cylindrical outlet-pipes communicating at one end with the delivery-pipe and opening at the opposite end into the closed chamber, said cylindrical pipes being concentric with each other and the innermost pipe being arranged at the greatest distance from the steam-pipe, substantially as described.

2. The combination, with the closed chamber having a supply-pipe 2 and a deliverypipe 15, of a steam pipe 6, extendinginto the closed chamber, and cylindrical outlet-pipes 9, l0, and 11, extending successively farther into the closed chamber and terminating at a short distance from the inner end of the steam-pipe, said cylindrical pipes being concentric With each other and having their axes in line with the axes of the steam-pipe and delivery-pipe and the innermost cylindrical pipe arranged at the greatest distance from the inner end of the steam-pipe, substantially as described.

3. The combination, with the closed chamber having a supply-pipe 2 and a deliverypipe 15, of a steam-pipe 6, extending into the closed chamber at one side thereof, and a series of cylindrical concentric pipes 9,10, and l1, supported by the opposite side ofthe casing and interposed between the steam-pipe and the delivery-pipe, the innermost cylindrical pipe being arranged at the greatest distance from the inner end of the steam-pipe, substantially as described.
